Application filed March 17, 1921; Serial No. 453,173.

means whereby substances or articles commo'nly used by dentists may be conveniently supported and readily brought into position to be heated. More particularly my object is to provide means whereby the various substances and articles used in the preparation of novocain may be supported, heated or otherwise treated.

In carrying out my invention I provide .a stand comprising a base. an upright or standard, and one or more arms or brackets which extend laterally from V the I standanl and which support test tubes, flasks, or other such devices.

These arms are associated with a heater, such as an electric heater, an alcohol lamp,'or Bunsen burner. The base is preferably circularin outline, and the heater is placed eccentrically on the base. The standard is also placed eccentrically on the base' and the brackets are of such construction that they may support the test tubes, flasks, fetc., in such manner that they may be brought successively or as desired over the burner. It is important that the devices should be kept perfectly clean or free from dust, and in order to do this I provide a cover for them which is preferably transparent and may be i an ordinary bell jar of well known lorni. Provision is made for attaching the cover to the base in such manner that it may be tightly held thereon so that by lifting the cover the base and the entire appliance may be lifted and moved. The cover may, be quickly detached from the base when desired.

In the accompanying drawings Figure l is a perspective view of the apparatus embodying my improvements.

Figure 2 shows .a transverse section through the transparent cover with the other parts of the apparatus in plan.

Figure3 is a bottom view of the apparatus.

Figure 4 is a View, partly in vertical section and partly in elevation 0t some ot the parts.

The apparatus as a whole constitutes what maybe called a novocain unit, being pro;

preferably placed at one side of the center of the base and may be pivotally connected therewith. i brackets C, D, E and F whichin turn support flasks, test tubes, etc.

jar is removably supported on the base and it has a knob or handle 9 as usual. In order to detachably attach the cover to the base the. latter is provided with fixed hooks H, H adapted to engage the rim 9 of the cover and with a movable hook H also adapted to engage the rim 9. The hook H is formed onthe outer end otan'arm h pivoted eccentrically [at i to the base. turning the arm h'to the proper extent, the'hook H may be withdrawni'rom the cover and the latter The P upports arms or.

A transparent. cover Got the kind commonly called aBell removed or by turning thehookto the position shown in Figure 2 the covermay be securely locked to the'base. A suitable heater K is supported on the base somewhat to one side of thebase center. Thisheater may be an electric heater, an alcohol lamp or as l is extending under the base and supported by a bracket 71;. The pipe is is detachably connected with a supply pipe L. The standard, as before stated, may be pivotally connected with the base, but prefthe rod is threaded as shown to receive a nut 6 The upper end of the rod]; is also threaded and receives an adjusting nut B.

shown aBunsen burner supplied by av pipe By tightening the nut, the brackets or arms are held securely in the position to which they are adjusted. By loosening the nut, the

arms may be turned to the desired extent.

The lower arm or bracket C is preferably provided with posts 0 to center a flask M of special form and called a Ringer flask consisting oi a body 772,, a spout m, a filling neck m and a flattened ring m through which a flat blade may be thrust and thus the flask handled with ease While hot. The arm I Thebrackets E and F are adapted to support test tubes 0, P or any other devices which it is desired to heat. All of the brackets or arms may be turned to any desired eX- tent in either, direction to properlyadjust them to bring anyone of the elements over the heater and aWay therefrom.

When in use the cover is of course removed. Ready access may be had to any part of the apparatus and each element may be moved into position-for use or out of'the Way With great facility. Whenthe heat is turned off and'the apparatus is not. being used, the cover may be quickly applied and securely locked, so that the different parts ofthe apparatus Which it is desired tokeep clean are protected from dust and other contamination.

'lclaim as my invention 1. A dental apparatus, comprising a base, a heater supportedby the base, a post on the base and extending vertically'therefrom, brackets carried by the-post and projecting laterally therefrom, a cover having a laterally projecting rim at its lower end and means for d'etachably locking the cover'to the base, comprising hooks fixed to the base and Which engage-the rim of the cover and a hook carrying arm on theunder side of the base and pivoted eccentricallythereon, being adapated to engage the rim of the cover or to become. disengaged therefrom, whereby When saidarm engages the cover, the basewith parts carried thereby may be lifted with the cover.

2. A. dental apparatus, comprising abase,

a heater supported on the base, a post mounted on the base and extending vertically therefrom, tube supporting brackets supported by the post projecting laterally theret'rom, located in different horizontal planes the cover to the base, comprising hooks fixed to the base Which engage the rim of the cover and a hooked arm on the under side of the base and eccentrically pivoted thereto. I

3. A dental apparatus comprising a base, a heater supported on the base, a post mounted on the base eccentrically comprising a rod and spacing sleeves, brackets supported by the post projecting laterally therefrom and located in dili erent horizontal planes, and a lid carried by one of said brackets adapted to cover a container supported by said bracket.

4. A dental apparatus comprising a base, a heater carried thereby, a post mounted on the base, a bracket extending laterally :rom the'post and provided With centering posts and having an opening through it to expose the bottom of a flask centered between the posts, another bracket carried by the post for supporting a dissolving tube and Which hasa hinged lid, and other brackets inho'ri Zontal planes above the others which are mdependently movable about the axisot the post and which are adapted to support test p tubes or thelike over the heater.

In testimony whereof, I have hereunto subscribed my name.
